(十四)SpringBoot2.0整合Actuator监控管理及Admin-UI分布式微服务监控中心

一. Actuator监控应用

Actuator是spring boot的一个附加功能,可帮助你在应用程序生产环境时监视和管理应用程序。可以使用HTTP的各种请求来监管,审计,收集应用的运行情况.特别对于微服务管理十分有意义.缺点：没有可视化界面。

1.1 Maven依赖

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>

1.2 yml配置

###通过下面的配置启用所有的监控端点，默认情况下，这些端点是禁用的；
management:
  endpoints:
    web:
      exposure:
        include: "*"
###接口 相当在配置文件中，配置相关info开头的配置信息
info:
  hszsd: 合石招商贷
  name: 何金荣

1.3 Actuator访问路径

通过actuator/+端点名就可以获取相应的信息。

1.4 启动

http://localhost:8080/actuator/info
可以访问到自己定义的字段属性。

二. Admin-UI分布式微服务监控中心

Admin-UI基于actuator实现能够返回界面展示监控信息

2.1 Admin-UI-Server

2.1.1 maven依赖

<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.3.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<properties>
		<java.version>1.8</java.version>
		<spring-boot-admin.version>2.1.3</spring-boot-admin.version>
	</properties>

	<dependencies>
